South Park (just love it)
Xenon
and some other early '80s one that I can't remember the name of.... or much else of; this was a loooooong time ago. It had a Space theme, and a maze-like thing at the top... you had to hit targets to spell a word (something like blast off) and then you could advance your way through the solar system.... or something like that... been over 15 years since I've seen it...
